I am a 46 year old Cat 4 road racer. My mechanic recently dropped my handlebars down about a centimetre because there was a small crack in the carbon stem. He didn't think I would notice a difference riding, and I thought it might give me a more aerodynamic position. For short rides (10-20 miles) I don't notice much, but after longer rides both my lower and upper back are very sore. Is this something my back will get "trained" for over time, or am I risking long term back problems by continuing to ride this way? I've been riding in the lower position about three weeks.

The answer to that is as clear as mud. If you have read through the archives you will note that I am fairly keen on the rider bearing the great majority of their weight underneath their backsides and not using any more effort than the minimum necessary to steer and control the bike. The short answer to why that is, is that it gives the rider the best chance of optimising how their central nervous system prioritises efficient muscle enlistment patterns for cycling.

Most commonly available shoes have low-ish heel lifts in the last at the moment, though some are lower than others. The basic issue is this. High heel lift cycling shoe lasts tend to require more ankle movement from riders whose natural technique is to drop their heels noticeably while pedaling under load. The amount of torque a rider can exert on a crank arm changes as the crank rotates and the peak value is at or near the 3 o'clock position of the crank arm. The 'problem' we are all trying to solve is how to get behind and over the pedal axle at the earliest possible point in the pedal stroke after top dead centre (TDC) which is 12 o'clock.

Saddle to bar drop and reach is nearly identical. I have been doing Z4 efforts (TT pace) all winter and spring so I have a pretty good idea of what I can ride at for 20-30 min. I did an 18 min power test in late January at 325 watts and my coach estimates a FT of 309 (what I could put out for only 20 min a year ago). I have been doing 3x 10 min Z4 efforts separated by 1 min rest and 20 min Z4 in training at between 315 and 325 watts for the past month or so. All of this was done on my road bike. I have been working on getting my TT bike set up.

I have always heard that if your position is too extreme that you will loose power by either over extending, creating too acute of angles or cutting of blood flow. I progressively made my position more aero until I did a 20 min Z4 effort and saw some real power loss (295 watts), got a terrible side stitch and had to stop. Then I went backwards and moved it to a slightly less aero position by raising the bars up by 5mm. Now I feel really comfortable with the position. My back seems flat, arms are flat and my knees are tucked right behind my elbows. This past weekend I did my first in competition TT on the bike and held 323 watts for 28:47 min over 20k. I feel like 323 is close enough to the power I am putting out in training especially given the time was longer and with less rest then I do in training.

I have also heard that because the TT position is further over the bottom bracket that it is possible to put out even more power on the TT bike then on the road bike, if that is true, then how do you account for that between the two bike positions? I don't have a wind tunnel so everything I do has to be experimental on the roads. So my question is how do you better determine if your position is optimal? Is it a guess and check to see if power is being lost?

I am a bi-lateral testicular cancer survivor (lost both of my testicles to cancer), so my body doesn't produce any where near the normal amount of testosterone for my age, 30. I take Androgel every morning. It's a gel that I rub on my shoulders and abdomen. I get my testosterone levels checked regularly to ensure they are normal and near my naturally occurring level of 610 (taken after the first surgery and when I found out I'd be losing the second testicle). I understand that my natural levels can vary for many reasons, time of day, activity level, etc., so 610 is just one data point.

I would imagine that for you, a very special case, it would be possible to attain a therapeutic use exemption (or 'TUE') for your testosterone supplement. I'm not the authority on such things, but since your body does not produce the testosterone, I would only imagine the anti-doping folks would agree to let you use the supplement in competition. My guess would also be that if tested, your testosterone levels would have to fall in line with certain parameters - probably also outlined in your TUE.
